For about $60 in materials and a little elbow grease you, too, could set up your very own FabFi metropolitan area network node. What’s the catch? You’ll have to build it yourself. Fear not, because everything you ever wanted to know about setting one up is available on their wiki. Starting as an open source project within MIT’s famed FabLab, FabFi has grown production networks actively deployed in four locations across two countries. [via übergizmo]
